GUIDE ATTACHMENT TO RQLLING -MILLS.

, Specification of Letters Patent.

Patented Aug. 1, 1905.

Application filed October 1, 1904;. Serial No. 226,779.

To all whom it may concern.-

Be it known that I, ALEXANDER M. J OHN- STON, acitizen of the United States, residing at Crafton, in the county of Allegheny and State of Pennsylvania, have invented certainnew and useful Improvements in Guide Attachments to Rolling-Mills; and I do hereby declare that the following is a full, elear,,and exact description of the same, reference being Figure 1 is a top plan view of the guide at-' tachment constructed in accordance with my invention; Fig. 2, a longitudinal section taken on line 2 2 of Fig. 1; Fig. 3,'a trans verse section taken on line 3 30f Fig. 2 looking in the direction of the arrow, the grooved rolls and set-screws being shown in elevation. Fig. 4; is a perspective view of one of the guide-sections; Fig. 5, a similar view of one of the wedges for adjusting the height of the guide.

In the accompanying drawings, A represents the guide-box, which may be of any suitable size and construction, which is provided with suitable clamping-screws a or any other preferred means that will securely hold the box down upon a support or other stationary object. guide-grooves Z) to receive the wedge-shaped adjusters B. (Shown in detail in Fig. 5 of the drawings and which will be hereinafter more fully described.)

The guide for the rod is formed in two longitudinal separable sections 0 D, having each a semicircular groove 0 upon its inner side, and has a socket d, in which is located a grooved roller E, held therein by a suitable box e or by any other preferred means. The sections C D are adjustably held together within the box by suitable set-screwsf, preferably four in number, although any number of setscrews may be used, as found most desirable,

The box A is formed with the grooved faces of the sections being opposite each other, as shown in Fig. 3 of the drawings. The guide-sections C D at their forward ends are reduced in shape to correspond with the shape of space between the -meeting peripheries of the rolls of the mill,

as shown at g, so that the reduced ends of the sections will enter between the rolls nearly to the point where the rolls take the metal.

Through themedium of the set-screws f the two separable guidesections 0 D may be adjusted laterally and held in their adjusted position, the set-screws 7 extending down through the top of the box A, holding the guide-sections firmly in place after being adjusted laterally. The set-screws it have washers i, and said screws extend down through a frame F, having an elongated slot j to allow the set-screws to be moved laterally to adapt them to the position of the guide-sectionsG D when moved laterally, and upon the ends of the set-screws are nuts 70.

In describing the set-screws f and h I do not desire to be understood as limiting my invention to the particular means shown for adj usting and holding in adjustment the guide-section, as any suitable means may be substituted as found most practical.

A block Gr, preferably of steel, is employed and placed between the heels of the guide-sections and the slotted cleat H to prevent the guide-sections from slipping back out of posi-' tion.

The wedge-shaped adjusters B, as shown in Fig. 5 of the drawings, have a screw-threaded I shank Z to receive a washer m and screw-nut may be resorted to in the general construction of the attachment without departing from the essential features of the invention.

Having now fully described my invention,

- What I claim as new, and desire to secure by Letters Patent, is-

A guide attachment for rolling-mills, comprising a box or frame and a guide adjustably held therein, said guide comprising two separable longitudinally grooved sections each having a grooved roller in which the groove height of the guide, substantially as and for is on line with the groove in the section, a the purpose set forth.
